An unusual case is reported in which an anterior communicating artery (A-Co-A) aneurysm was associated with a large calcified pituitary adenoma. A 59-yr-old woman was admitted to the Fujisawa City Hospital SAH by lumber puncture. Neurological examination revealed a slightly disoriented patient with mild nuchal stiffness. Optic fundi were atrophic bilaterally and she had diminished visual acuity with temporal hemianopia of the right eye. Neuroradiological studies, including skull X-ray film, cerebral angiogram and computed tomography scan, revealed ruptured A-Co-A aneurysm associated with intracellar calcified tumor extending to the supracellar region. A craniotomy, through the left fronto-temporal region mode was made the aneurysm was successfully clipped rat and the tumor partially remove. Microscopically the specimen showed laminated calcospherites surrounded by small round or cuboidal cells with ovoid nuclei which yielded a pathological diagnosis of calcified chromophobe adenoma. Coexistence of aneurysm and brain tumor and etiology of the calcified pituitary adenoma are discussed.
